Specification of Letters Patent.

Application filed May 18, 1905. Serial No. 261,012.

To all whom it may concern.-

Be it known that I, JOHN DOERTNG, a citizen of the United States of America, residing in the borough of Brooklyn, city of New York, county of Kings, State of New York, have invented an Improved Lantern, of which the following is a specification.

The object of my invention is to provide an improved construction of lantern which shall be very strong yet economical to make in the guard-frame and in the hinging of the cover, will give a good system of draft without danger of the flame being blown out, and will permit the oil-pot to be withdrawn from the bottom of the lantern and yet permit the wick to be raised or lowered without withdrawal of the oil-pot.

In the accompanying d rawings,'Figu re 1 is an elevation of my improved lantern. Fig. 2 is a sectional plan on the line 2 2, Fig. 1. Fig. 3 is a vertical section view on the line 3 3, Fig. 1, but showing the oil-pot being withdrawn. Fig. 4 isa sectional plan on the line 4 4, Fig. 3. Fig. 5 is a similar plan view with the oil-pot adjusted to position and with the frame omitted. Fig. 6 is a face view of diaphragm taken from the hood, and Fig. 7 is a view of a detail.

In the figures, A is the guard and supporting frame; B, the globe; 'C, the globe-supporting ring; D, the oil-pot, and E is the top or cap, which is hinged at one side 0 to the top ring A of the guard-frame and at the other side has a spring-latch e to engage the top ring A to hold the cap in its closed position.

The construction of the guard-frame is one of the features of my invention. This frame is composed of a series of flat metal upright strips or bars 5 6, arranged in pairs side by side for about two-thirds of their length from the bottom upward and preferably riveted together, but with their upper ends 5 6 branched laterally to 'meet the adjacent branched bars of the adjacent pairs. The upper ends of these united branches 5 6' are riveted or otherwise secured to the top ring A, which is preferably flanged. The lower ends of the strips or bars 5 6 are shaped with an outward flare, as shown in the drawings, to form a base for the lantern of suitable diameter, and they are united and at the same time spaced by a bottom ring of wire A The described construction of guard-frame is very strong and rigid.

The globe-supporting ring C is preferably formed of two sheet-metal rings 03 d spun over each other, with an inwardly-projecting flange 7 at the lower end to receive and sup port the oil-cup and with outwardly-projecting lugs 8 radially notched toreceivetheinwardlyprojecting parts of the united pairs of strips or bars 5 6. The lugs 8 are long enough to have their outer ends wrapped over a wire 9,

which passes through all the bars 5 6.

The oil-pot is formed with a slightly-reduced upper part 10 and an annular shoulder 11, the reduced part 10 fitting within the flanged lower end of the ring 0, which supports the globe B. On the upper edge of this reduced part 10 I provide two diametrically opposite lugs 12 13, and at one side the flange 7 is cut away at 14 to permit one of these lugs 13 to pass throughit. To put thelamp in place, one of the lugs 12 is introduced over the flange 7 at a point diametrically opposite the notch 14, whereupon the oil-pot may be tipped upward, as indicated by the arrow in Fig. 3, to pass the other lug 13 through the notch 14 in the flange 7 and at the same time the laterally-projecting wick-raising spindle 17 passes up into a notch 15 cut in the ring C, as indicated by dotted lines in Fig. 3 and partially by full lines in Figs. 4and 5. Then the oil-pot is turnedsay in the direction of the arrow, Fig. 4so that the lug 13 will pass laterally away from the notch 14 and into engagement with the flange 7, locking the oil-pot in place with an action like that of a bayonet-joint. To permit this turning movement of the oil-pot, the burner 16, with its wick-raiser 17, is not screwed up tight to its seat when the pot is being introduced into the lantern, as shown in Fig. 3, so that the turning of the oil-pot in the direction of the arrow, Fig. 4, and to the position Fig. 5 while the wick-raising spindle is held in the notch 15 will serve to screw the burner to its seat. The friction will hold the parts in position until the oil-pot is intentionally turned back to take it out of its carrying-ring by movements the reverse of those by which the pot was put in place. The described construction of oil-pot attachment is designed to prevent any material admission of air-draft to the flame from below, the top admission hereinafter described being relied on to feed the flame.

The cap or top E has the usual cylindrical dome 20, closed at the top, with outlet draftopenings 21 near the top, and it has also the usual reflector part 22. Within the dome is an annular diaphragm 23, with a series of pass upward in a central column and out through the center of the diaphragm 23 into the dome. A draft-producing cone 26 may be provided over the diaphragm 23, and a ring of holes 27 may be made in the diaphragm 23 to admit air to the dome outside and also inside the cone. The diaphragm and cone may be secured together, and they can move up and down within the dome; but a light spiral spring 28 within the dome presses the diaphragm down onto the globe.

As a convenient way to hinge the cap E to the frame I split the top ring A and flange its adjacent ends at 30, and I rivet to the cap a lug 31, which passes between the flanges 30, Figs. 1 and 3. A hinge-pin formed of a detachable nut and screw 32 completes the attachment, so that the cap E may be wholly taken off when required.

The bail F may be secured to the lantern in any suitable way, as by bending adjacent branches 5 6 to form sockets f for hingepins 33 on the ends of the bails, Figs. 1 and 7. These branches may be riveted together at 34:.

I claim as my invention- 1. A guard-frame for alantern, comprising a series of upright bars in pairs with their upper ends branched laterally and joined to ad-. jacent branches and with top and bottom rings.

2. A guard-frame for alantern, comprising a series of upright bars riveted together in pairs and branched laterally at their upper ends, a bottom ring spacing the pairs, and a top ring to which the tops of the bars are riveted.

3. In a lantern, the combination of a guardframe, with a globe-holding ring in two parts spun over each other, one part presenting outwardlyprojecting lugs connecting to the guard-frame and the other part projecting inwardly to form an inwardly-projecting flange to support the oil-pot.

4. In a lantern, the combination of aframe and notched ring with an oil-pot detachable from below and having a wiclcraiser and a burner screwed into the oil-pot, the wickraising spindle being adapted to enter the notch in the ring and to be accessible from the outside of the lantern, and a bayonet-joint to secure the oil-pot in the frame with a rotary motion of the oil-pot, the said burner being adapted to be screwed into the oil-pot by turning the latter into the bayonet-joint.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN DOERING.
